摘      要：Current mirror integration（CMI） read out integrated circuit（ROIC） topology provides a low input impedance to photo-detectors and provides large injection efficiency, large charge handling capacity and snapshot mode operation without in-pixel opamps. The ROIC described in this paper has been implemented with a modified current mirror circuit, with matched PMOS pairs for detector input stage and its biasing. The readout circuit has been designed for 30×30μm^2 pixel size, 4×4 array size, variable frame rate, 5 Me charga pixel per second（Mpps）.Experimental performance of the test chip has achieved 15 Me charge handling capacity, a high dynamic range of83 dB, 99.8% linearity and 99.96% injection efficiency. The ROIC design has been fabricated in 3.3 V 1P6 MUMC180 nm CMOS process and tested up to 5 MHz pixel rate at room and at cryogenic temperature.
